PRODUCT: WHITE Seam Tape / Doublestick. Double-sided WHITE Butyl Rubber Based Seam Tape. Weatherbond Brand. 35 mil Thick, 3-inch Wide X 100' Roll. Price/Roll. APPLICATIONS: Seam Tape is applied between overlapping seams to seal seam and provide long-term integrity and strength to these areas. Must be used with EPDM Primer. DESCRIPTION: WeatherBond EPDM Rubber Seam Tape is a two-sided, cured Butyl rubber based polymer adhesive that offers uniform width and adhesive thickness.WeatherBond EPDM Rubber Peel & Stick Seam Tape delivers 30% greater peel strength and 32% greater shear strength when compared to other tapes available in today's marketplace.Designed use with all type of EPDM Rubber roofing membranes with Fully-Adhered systems, WeatherBond rubber Peel & Stick Seam Tape must be used in conjunction with Multipurpose Primers to fuse EPDM membranes together in the field for long-term splice strength.INSTALLATION:SEAMING
USING SEAM TAPE - The EPDM roofing membrane should be positioned so that
the width of the seam is 3”.Remove
excess chalk from a chalk line by snapping the line into the air and then
chalk a line one-quarter (1/4”) to one half inch (1/2”) from the leading
seam edge. Fold the
top sheet back to expose the seam area. Using the
medium nap paint roller apply the WeatherBond Multipurpose Primer to the
seam area using back and forth strokes with moderate pressure until the
seam surface attains a smooth black appearance. Apply the
WeatherBond Multipurpose Primer past the seam edge to the chalk line.
Allow the Primer to fl ash off. NOTE: If
the EPDM membrane is contaminated with dirt, dust, or debris, clean the
seam area with Membrane Cleaner before applying WeatherBond Multipurpose
Primer.Unroll the
3” wide Seam Tape along the length of the seam, tape side down, aligning
the Seam Tape (not the clear backing) along the chalk line. Using
moderate pressure set the Seam Tape into place to keep air from being
trapped under the tape. Fold the
top membrane onto the Seam Tape release paper. (If the Seam Tape does not
visibly extend beyond the leading seam edge, the membrane edge should be
cut back to expose one-quarter inch (1/4”) of Seam Tape.)Reaching
under the top ply of membrane, pull the release paper away from the Seam
Tape at a 45-degree angle to the seam. While
removing the paper, draw your hand across the seam, from the back to the
leading edge. This will prevent wrinkles and fish mouths from forming in
the seam. After the
paper is removed, roll the entire length of the seam with a steel or
silicone hand roller, first, across the seam, and then the length of the
seam. NOTE: When
splicing Seam Tape, overlap each piece a minimum of one inch (1”) and
firmly roll with a steel or silicone hand roller. Apply lap sealant along
the seam’s leading edge 3” in each direction from where the seam tape is
spliced together.SUMMARY:
